Answer:
Protons= 17, Electrons= 17, Neutrons= 18
Explanation:
The atomic number (Z) corresponds to the number of electrons that is equal to the number of protons (17). The mass number (A) corresponds to the sum of protons and neutrons present in the nucleus (35). Therefore, we calculate the number of neutrons: 35-17 = 18
An example of the substnce would be steel
Isotopes are atoms with different number of electrons
isotopes are very useful
for example isotope of uranium is used in atomic bombs and nuclear reactors radioactive isotopes are used to date ricks soils and archaeological objects.
isotopes have many uses that's why we study isotopes to know their uses
